Crate ukernel_sys 

System interface types for µKernel.

This crate defines the ABI between userspace domains and the µKernel microkernel. It contains:

• KernelOp — the ~30 primitive kernel operations
• SubmitEntry / CompleteEntry — submission ring entry types
• SubmitRing — shared-memory ring buffer layout
• SubsystemId — hashed subsystem identity for loadable domain types

Architecture

Application (Rust std or no_std)
    ↓
libposix.a (queues KernelOps into ring)
    ↓ SYS_SUBMIT
µKernel (processes ring, capability checks)

This crate defines the types at the ↓ boundary. It is no_std and has zero dependencies.

Usage

Most applications don’t use this crate directly — they use Rust std (via the x86_64-americankernel-ukernel target) or libposix. This crate is for:

• Building custom domain runtimes
• Writing kernel-level drivers or subsystems
• Understanding the µKernel syscall interface
